Penguin Overlords

The world is ruled by the turtles and the only enemies are penguins who fight back. Penguin Overlords won't get any Oscar for story but that's not important. The whole game is separated into two parts. The first is about improving and buying better penguins. The second is the fighting moments. To reach the higher levels you have to eat all the turtles. Their number and type is always bigger and better.
